[0017] See also Figure 1-Figure 2The utility model provides a technical solution: a motor stator press-fitting device, including a press-fitting table 1, a positioning groove 11 is opened in the middle of the upper surface of the press-fitting table 1, a pressing plate 17 is horizontally arranged above the positioning groove 11, and also includes a top plate 12, the top plate 12 is horizontally arranged on the inner side of the positioning groove 11, and a detection mechanism is arranged above the top plate 12; the detection mechanism includes a support block 21 and a pressure sensor 22, a detection groove 2 is opened on the upper surface of the top plate 12, the detection groove 2 is slidably connected to the bottom side of the support block 21, and the pressure sensor 22 is fixedly connected to the middle of the inner wall of the bottom end of the detection groove 2.

[0018] In this technical solution, the pressure of the motor housing on the upper surface of the support block 21 can be detected by the pressure sensor 22, and the pressing condition of the stator by the pressing plate 17 can be further detected, thereby controlling the second cylinder 16 to pull the pressing plate 17 upward to reset, and at the same time controlling the first cylinder 13 to work, pushing the top plate 12 upward, and pushing the pressed motor housing and electronics to move upward and out of the positioning groove 11. This can solve the problems of the existing motor stator pressing device, which is inconvenient to control the pressing force of the stator and inconvenient to collect the motor housing and electronics after pressing.

[0019] In this embodiment, the middle part of the bottom side of the press-fitting table 1 is fixedly connected to the first cylinder 13 by bolts, the telescopic end of the first cylinder 13 passes through the bottom inner wall of the positioning groove 11 and is fixedly connected to the middle part of the bottom side of the top plate 12, the pressure sensor 22 abuts against the middle part of the bottom side of the support block 21, and the sizes of the positioning groove 11 and the top plate 12 match.

[0020] In this technical solution, when the squeezing force of the motor housing on the support block 21 reaches the threshold of the pressure sensor 22, it means that the stator is pressed into the motor housing, and the pressure of the mounting plate 15 acts on the motor housing. At this time, the pressure sensor 22 can transmit data to the corresponding controller, and the corresponding controller can further control the second cylinder 16 to drive the pressure plate 17 to move upward and reset. At the same time, the corresponding controller can control the first cylinder 13 to work, and can push the top plate 12 to move upward, thereby pushing the pressed motor housing and electronics to move upward and out of the positioning groove 11, which is convenient for the staff to collect.

[0021] In this embodiment, columns 14 are vertically fixedly installed on the four corners of the upper surface of the press platform 1, and a mounting plate 15 is horizontally arranged above the press platform 1. The top ends of the four groups of columns 14 are respectively fixedly connected to the four corners of the bottom side of the mounting plate 15. The middle part of the upper surface of the mounting plate 15 is fixedly connected to the second cylinder 16 by bolts. The telescopic end of the second cylinder 16 passes through the bottom side of the mounting plate 15 and is fixedly connected to the middle part of the upper surface of the pressing plate 17. The column 14 vertically passes through the pressing plate 17 and is slidably connected to the pressing plate 17.

[0022] In this technical solution, the second cylinder 16 is controlled to work, so as to push the pressing plate 17 to move up and down smoothly above the pressing table 1, thereby improving the pressing stability of the stator.

[0023] When a motor stator press-fitting device is used, the motor shell to be press-fitted is placed in the positioning groove 11 and placed on the upper surface of the support block 21. The second cylinder 16 is controlled to work, which can push the pressing plate 17 to move downward, and further press the stator above the motor shell into the motor shell to realize the stator press-fitting operation. The pressure sensor 22 can detect the pressure of the motor shell on the upper surface of the support block 21, and further detect the press-fitting condition of the stator by the pressing plate 17. When the squeezing force of the motor shell on the support block 21 reaches the threshold of the pressure sensor 22, it means that the stator is pressed into the motor shell, and the pressure of the mounting plate 15 acts on the motor shell. At this time, the pressure sensor 22 can transmit data to the corresponding controller, and the corresponding controller can further control the second cylinder 16 to work and drive the pressing plate 17 to move upward and reset. At the same time, the corresponding controller can control the first cylinder 13 to work, which can push the top plate 12 to move upward, thereby pushing the pressed motor shell and the electronics to move out of the positioning groove 11, which is convenient for the staff to collect.
